[Serusers] fr_inv_timers affect on inbound/outbound calling

[Jiri Kuthan]

We indeed contemplate this feature from time to time. We haven't

the current status. There have been some issues reported to
use with too dense DB operations over UsrLoc: mysql was told
to slow down after it fragmented its database.
